SPECIFICATION forming part of Letters Patent No. 533,638, dated February5, 1895.

Application filed September 5,1894:- Serial No. 522,158- (No model.)

T0 aoZZ whom it may concern.-

Be it known that I, FRANK B. DAVIDSON, of Chicago, in the county of Cookand State of Illinois, have invented certain new and usefulImprovementsin Cartons; and I do hereby declare that the following is a full, clear,and.

exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to improvements in paper or straw board cartonsfor use in packing candy and other articles in barrels, pails, or otherreceptacles of circular cross-section.

The object of the invention is to provide an improved construction indevices of the character referred to, and it consists in the mattershereinafter set forth and particularly pointed out in the appendedclaims.

A carton embodying my invention is composed of sector shaped cells orcompartments which are formed by a plurality of radius walls arranged toradiate from a common apex or center, and are walls which connect theradius walls and are provided in pairs of equal and similar sectionsadapted to fold upon their lines of juncture with each othersimultaneously with the folding of the radius walls about their apexes,so that the carton as a whole may be collapsed or folded flat fortransportation or storage.

In the accompanying drawings, Figure 1 is a top plan View of an extendedcarton constructed in accordance with my invention. Fig. 2 is a similarview of the same when partially collapsed. Figs. 3 and 4 show theconstruction of the blanks fromwhich the carton is formed. Fig. 5 is atop plan view of a sector shaped carton somewhat modified inconstruction from that previously shown. Fig. 6 is a side elevationthereof. Fig. 7 is a top plan view of a double carton formed byconnecting together two of the cartons shown in Figs. 5 and 6. Fig. 8illustrates the blank from which the modified carton is formed. Fig. 9shows the carton as it appears when partially collapsed. Figs. 10, 11,and 12 illustrate a still different construction embodying the. samegeneral principles. Fig.13 is a top plan view of a carton having but twocells.

In said drawings (Figs. 1 to 4), A designates the carton as a whole, andA A the sector shaped cells or compartments into which it is divided.One of said cells, the cell A in this instance, is complete in itself,being formed from an elongated strip or blank B the ends of which arebrought together and secured to each other by means of a paste strip 6,or otherwise as desired. Said blankis folded upon suitable transversescore lines I) which divide it into four sections a a a a. Of these thesections a a are equal and similar to each other and form the radiuswalls of the sector shaped cell, while the sections a a form the arcwalls of the cell and are also made equal and similar to each other, butwill ordinarily be of considerably less length than the radius walls aa. In any case, however, the combined length of one radius wall and itsadjoining arc will obviously be exactly equal to the length of the otherradius wall'and its adjoining arc wall. Consequently, the cell is freeto be collapsed or flattened by the folding together of the radius wallsabout their apex a. and of the arc walls about their juncture a untilthe two walls forming each pair are brought into contact with eachother, whereupon the cell will lie perfectly flat and will occupy theleast possible space in storage and transportation.

The second cellor compartment A is built upon the primary cell A, thusdescribed, by the attachment thereto of a second blank B, which isprovided at its opposite ends with paste strips B, said strips beingsecured to the exterior surface of one of theradius walls a of theprimary cell at the opposite ends thereof. The blank B is also foldedupon score lines I) which divide it into three sections at a a which areexactly like the correspondingly lettered sections of the blank B andwhich form the outer radius wall and the.

two are walls respectively of thenew cell, its other radius wall beingformed by the wall of the primary cell to which the blank B is secured.

Other cells A may be provided in the same manner as the second cell,above described, by the attachment of additional blanks B. to the cellspreviously formed, and in this way a carton comprising any desirednumber of compartments may be constructed. Such carton, as a-whole, aswell as each cell or compartment thereof, will obviously be of sectorments will be brought into contact with each other, and the center angleas a whole will comprise three hundred and sixty degrees, oracompletecircumference. Othernumbersof cells of diiferent apex anglesmight, however, be employed, and cartons embracing but a semi-circle,more or less, may be constructed if desired. In any case,l10W6V6I',-83.Ch'0f the several cells may obviously be collapsed in thesame manneras the primary cell, so that no matter what the size of thecarton or thenumber of cells included therein it might be 2 5 collapsedor folded flat for storage and trans portation.

In Figs. 5 to 13 inclusive I have shown a construction somewhat modifiedfrom that heretofore described, in which a carton em- .30 bodying myinvention in another form is made from a single strip or blank ofuniform width by folding thesame in such manner as to form two or threecells which are substantially sector shaped in cross-sect ion, and areso 3 5 proportioned that when arranged with their apexes ata commoncenter two or more of the cartons will exactly cover a complete circulararea, and form one horizontal layeror zone in the pail orbarrel forwhich they are intended, and which at the same time are so constructedas to be capable of being folded or collapsed in substantially the samemanner as the cartons previously described. Preferably inthisconstruction also the blank will be so folded 4 5 as to form cellshaving an angle of sixty de'-' grees at their apex, in which case two ofthe three cell cartons or threeot' the two cell cartons obviously occupya complete circle, and

by pasting or otherwise securing such requisite number of cartonstogether the several cells occupying one horizontal layer may in thiscase be provided in what will practically .amount to a single carton.

As shown in Figs. 5 to 9, C designates a 5 three celled carton formed byfolding a single strip or blank D so as to bring its extremity at thejuncture of the interior radius sides 0 c with their adjoining arc sides0 c. The opposite end portions of the blank form the are sides of thetwo outer cells C, and the outer radius sides of said cells are eachmade continuous with the arc sides which adjoin them. At the apex c ofthe carton the meeting portions of the blank are made to cross eachother by means of slits a one of which extends half way across the stripstarting at its lower edge, while the other extends half way the acrossthe strip starting at its upper edge, the unsevered portion of the blankor strip opposite each slit being inserted in the opposite slit, asshown in Fig. 6. Each of the interior radius walls is thereforecontinuous with the remote exterior radius wall, butboth of saidinterior radius walls are continuous with the arc walls which connectthem and which obviously constitute the central portion of the blank.

In folding the blank to form the carton it is first looped at its middleportion to form the middle cell or compartment 0 its end portions beingcarried by each other far enough to permit their being crossed at theslits c Said end portions are then separately bent around to form theend cells C O and are attached to the outer ends of the interior radiuswalls 0 a by means of paste strips (1 which are provided on theextremities of the blank. Preferably, and as herein shown, each of thecells of a carton of this construction is made to include an apex angleof sixty degrees so that the entire carton is of semicircular shape andtwo of them onlyare required to fill one horizontal layer of the pail orbarrel -forwhich they are adapted. Accordingly,

they may be conveniently provided in pairs, pasted or otherwise securedtogether along 'two of their exterior radius walls, as shown in Fig. 7one such carton then'serving to form a complete layer in the receptacle.A carton of this construction may obviously be collapsed or folded flatin exactly the same manner as the circular carton first described.

. The carton in this instance illustrated in Figs. 5 to 9 is designedfor use in a receptacle which is slightly conical in form, or of greaterdiameter in one part than another, as for example, an ordinary bucket orpail; and to this end it is made slightly flaring or larger at its upperthan at its lower end so as to' conform more closely to the outline ofsuch receptacle.

The radius walls in this case will obviously be of slightly trapezoidalshape and the arc walls of slightly tapered shape, the blank D beingsomewhat curved or are shaped in its IIO The carton E, shown in Figs.l0, l1, and 12,

is formed by folding a single blank, substantially similar to the blankD, in a slightly different manner to that employed in forming the cartonC. In this case. the end portions 4 apexes of the two end cells E arethen brought I together and the space inclosed between their adjacentradius walls and said central portion of the blank forms, in efiect, thecentral cell or compartment E double carton of this form also may beprovided by pasting together two single cartons, as shown in Fig. 11.Such double carton will obviously serve to form one complete layer inthe receptacle, and may be collapsed or folded flat in the same manneras the previous construction. Its several cells, with the exception ofthe two whose radius walls are pasted together, will obviously not beattached at the common apex, but the wall of the surrounding receptaclewill maintain the carton in shape after it has been placed therein.

In Fig. 13 I have illustrated the manner in which a two celled carton F-may be formed from a single blank, the extremities of the blank in thisinstance occurring, one at the apex of its two cells F and the other atthe juncture of its interior radius wallf with its adjoining arc wall f.Three such cartons with sixty degree cells would obviously cover anentirely circular area and might be pasted together in the same generalmanner as the cartons illustrated in Figs. 7 and 11.

It will be understood that in Figs. 1, 7, and 11 the adjoining walls ofthe two end cartons have been left slightly separated for the purpose ofbetter illustrating the construction, although in practice they will bebrought into contact. Similarly in Figs. 2, 9, and 12 the severalcartons have been shown only partiall y collapsed for the same reason,although obviously capable of being entirely collapsed and flattened fortransportation and storage, as hereinbefore set forth. It will also beunderstood that the term sector shaped, as herein applied to the form incross-section of the cartons and cells, is not used in its accurategeometrical sense as comprising an area including an arc and two radiiof a circle, but is employed in a more general sense as the term whichmost nearly expresses the shape in cross-section of a carton in whichthe convex wall is formed by a plurality of plane surfaces whichapproximate to the theoretical curve of such wall sufficiently close forprac-' tical purposes, it being obvious that the curved wall required inthe construction of a theoretically perfect sector-shaped carton wouldbe difflcult to manufactureand would necessarily be distorted when'thecarton was collapsed or folded flat.

The cartons constructed as herein described have the obvious advantageover cartons heretofore made for the same purpose, of requiring aminimum amount of time or labor parts or flaps in order to set up thecarton in form for use. In a carton constructed as herein proposed nomanipulation of the parts to form separate cells is necessary, but, onthe contrary, the carton being itself complete in its knock-down orflat. form,all that is needed to open or expand it to its fullest extentis to spread apart its ends in order to prepare it for insertion in thepail, this being an operation requiring but an instant of time for itscompletion.

I claim as my invention 1. A carton,comprising a plurality of partitionwalls radiating from a common apex and flexibly connected with eachother at such apex, and are walls, two of which are permanentlyconnected with one of the radial walls, substantially as described.

2. A carton, comprising aplurality of partition walls radiating from acommon apex and flexibly connected with each other at such apex, andexterior walls connected with the radial walls and provided withintermediate folds or creases between the radial walls, whereby thecarton may be folded into flat form for transportation, substantially asdescribed.

3. A collapsible, sector shaped carton, comprising a plurality ofpartition walls radiating from a common apex at which they are flexiblyconnected with each other, and-exterior or are walls connected with theradial walls and provided with central folds or creases, each of theradial walls consisting of a single thickness of straw-board or thelike, and the arc walls being permanently secured to the outer marginsof the radial walls, substantially as described.

4. A collapsible sector shaped carton, com prising a plurality of cells,one of which is formed by securing together the opposite ends of ablank, and the other or others lot which are provided by securing theopposite ends of an additional blank or blanks to the cell or cellspreviously formed, all of the blanks being so folded as to provideradius walls arranged to radiate from a common apex, and are wallsprovided in pairs connecting the outer edges of said radius walls andadapted to fold upon their line of juncture when the radius walls arefolded about their apex, substantially as described.

5. A collapsible circular carton, comprising a plurality of partitionwalls radiating from a common apex and flexibly connected with eachother at such apex, and are walls connected with the outer margins ofthe radial Walls and provided with central folds or creases, the arcwalls being of such length that when extended they will form a completecircle and give circular formto the carton, substantially as described.

6. A sector shaped box or carton comprising a sector shaped cell formedby connecting the opposite ends of a blank and folding the latter toform two equal and similar radius walls connected to form an apex, andtwo I O 5 ALM equal and similar are walls connecting the outer ends ofsaid radius walls, and an additional cell or cells provided by securingthe opposite ends of another blank to the radius wall of a cellpreviously formed, such other blank being folded to form a radius sideradiating from the apex of the first cell, and two equal and similar aresides connecting the outer ends of said radius side with the outer endof the adjacent radius wall of the first cell,the are walls of all thecells being adapted to be folded together about their lines of juncturewhen the radius sides are folded about their apex, substantially asdescribed.

In testimony that I claim the foregoing as 15 my invention I atfix mysignature in presence of two witnesses.
